ATTOR N EY Patented Oct. 16, 1934 UNITED STATES PATENT OFFICE? 3 Claims.

This invention relates to adevice especially adapted for handling andstacking bundles of shingles, boxes and the like and has for the primaryobject the provision of a device of the above stated character which issimple in construction and in operation and only requires a minimumamount of power for its operation and also may be conveniently employedfor delivering already stacked bundles of shingles or boxes to a givenplace. I

With these and other objects in ,view this invention consists in certainnovel features of construction; combination and arrangement of parts tobe hereinafter more fully described and claimed.

For a complete understanding of my invention, ,reference is to be had tothe following description and accompanying drawings, in which Figure 1is a side elevation illustrating a device adapted for stacking shingles,boxes and the like and constructed in accordance with my invention.

Figure 2 is a similar view showing several positions the rack of thedevice may assume during the use thereof.

' Figure 3 is a similar view showing the device positioned afterarranging the bundles or boxes in stacked position.

Figure 4 is an end elevation illustrating the device. I

Figure 5 is a fragmentary sectional view showing means of adjusting therack into its many positions. v

Figure 6 is a detail sectional view illustratin the pivotal mounting forthe rack.

Figure '7 is a detail sectional view showing the means for releasing thepivotal mounting from .the rack.

Figure 8 is a perspective view showing aremovable pivot bar or journal.

Referring in detail to the drawings, the numeral 1 indicates a portablestructure consisting of a base 2 supported by ground wheels 3 andskeleton side frames 4. The frames 4 are substantially segmental shapedand provide arcuate shaped rack bars 5 extending from one end of thebase 2 and terminating in a plane'above the other end ,IOI the base.Operating between the side frames 4 above the base 2 is a rack or table6 of considerable length on which may be arranged in close relation aplurality of bundles of shingles or boxes received from a conveyor orsimilar device 7. The -rack or table 6 is detachably and pivotallyconnected adjacent one end to one end of the base 2.

{Brackets 8 are secured to the rack or table 6 and members 9 which ihave pivoted thereto link shaped rotatably and slidably receive a shaft10 extending transversely of the table or rack. Pinions 11 are securedto the shaft 10 and mesh with the rack bars 5 and journaled upon theshaft 10 are guide plates 12 carryingrollers 13 engaging the rack barsat an opposite side from the pinions 11. One of the guide-plates 12 hasjournaled thereto a pinion l4 meshing with a gear 15 secured to one endof the shaft 10. A crank handle 16 is secured to the pinion 14 wherebythe shaft 10 may be rotated with minimum effort on the part of theoperator for the purpose of raising and lowering the rack or table 6.

The pivot between the table and the base consists of brackets 1'7 ofhook shape to engage a shaft 18 carrying at its ends eccentrics 19rotatably mounted in bearing openings 20 formed in brackets 21 carriedby the portable structure 1. A crank handle 22 is secured to one of theeccentrics 19 for the purpose of rotating the cocentrics in theirjournals for the purpose of engaging and disengaging the shaft 18 withthe brackets 17. Thus it will be seen that the table or rack at one endmay be readily connected and 4 disconnected to the portable structure 1.

To load the table or track with bundles of shingles, boxes or the likeit is moved into a substantially horizontal position, as shown in Figure1, so that the bundles of shingles or boxes may be readily placedthereon. One end of the table or rack carries a stop plate 23 againstwhich is placed the first bundle of shingles or boxes when theassembling of the bundles of shingles or boxes is being made upon thetable or rack. After the desired number of bundles or boxes have beenarranged on the rack or table, the latter is swung into a verticalposition, as shown in Figure 3. The portable structure is then pulledaway from the stacked bundles or boxes, leaving them arranged in avertically stacked position. Thus it will be seen that a. large numberof bundles or boxes may be readily stacked with minimum effort. Insteadof employing the crank handle 16 for rotating the shaft 10, a suitablepower means may be connected to the pinion.

To employ the device for handling or loading already stacked bundles orboxes, the table or rack is arranged under the stack of bundles orboxes, as shown in Figure 3, and a pivot bar 24' may be placed betweenthe skeleton frames by occupying the notches 24 and the handle 22 isrotated to release the shaft 18 from the brackets 1'7, allowing thetable or rack to fulcrum on said pivot bar during its movement from avertical position to a substantially horizontal position, as

the part of the operator.

To facilitate the movement of ,the bundles or boxes on the table or rack6 the latter is provided with rollers 25.

While I have shown and described the preferred embodiment of myinvention, it will be understood that minor changes in construction,combination and arrangement of parts may be made without departing fromthe spirit and shown in dotted lines in Figure 2. The stacked bundles orboxes may then be conveniently removed to a given place with effort on2. A device of the character set forth comprising a portable baseincluding side members,

a bundle table, a journal rotatably and detachably connecting thetable'to the base for swinging movement between said side members andoutwardly of the latter, means between said side members and the tableto impart movement to the latter, and a journal removable from the sidemembers and to be engaged by the table when detached from the base.

3. A device of the character set forth comprising a portable baseincluding side members, a bundle table, a shaft eccentrically mounted tothe base, hooks carried by the bundle table to engage the shaft, meansfor imparting movement to the shaft for engaging and disengaging thelatter with the hooks, means between said side members and the table toimpart movement to the latter. and a journal removable from the sidemembers and to be engaged by the table when detached from the base.
